Embodiment Construction

[0019] The preferred embodiment of the invention is shown in the accompanying drawings. One end of the cylinder body 4 of the piston sensor has a connection interface. There is a power switch 9 at the switch position A of the cylinder body; there is a photoelectric switch circuit 3 formed by connecting and luminescent tubes 3a and 3b at its B place; the piston 6 of the piston sensor is provided with a seal 7 to prevent water leakage in the water purifier. Leakage, the piston is also sleeved with a back-moving spring 8, and is marked with an alarm mark on the top. The piston 6 can only move back and forth in a straight line in the cylinder body 4 . It is best to use low-friction combined seals for the seal 7, and can also use a lip-shaped seal with relatively stable friction, or an O-shaped seal. One end of back-moving spring 8 acts on the piston, and the other end acts on the cylinder body. The water purifier, the water inlet pipeline and the control valve constitute a filt...

Abstract

The invention relates to the water treatment industry, in particular to the aspect of the filtration and warning of a filter element. The invention discloses a detection and warning method of the pollution of a filtering layer of a water purifier, which comprises the following steps: providing the power supply of electrical energy needed by a system, also comprises a water pressure induction device for inducting the change of the water pressure of the filter element, a signal acquisition device for transforming a water pressure changing signal into an electrical signal, and a signal recognition circuit; a movable inductor of the water pressure induction system generates displacement under the effect of the water pressure of the detected filter element and the displacement triggers the signal acquisition device to be conducted; the recognition circuit carries out detection and recognition to the time of the lasting conduction of the conducting signal so as to judge whether a warning and prompting signal needs to be sent. The invention has simple method and easy operation, can actually reflect the state of the detected filter element, sends out the warning signal to prompt the user in time and ensures the safe use of the water purifier.

Description

[0001] Name of prior application: Filter layer pollution detection and alarm method Prior application number: 200710162777.8 technical field [0002] The invention relates to the water treatment industry, and specifically relates to the filtering alarm of the filter element. Background technique [0003] At present, water purifiers are relatively popular in China. For example, in terms of drinking water, water purifiers are used to deeply filter impurities in water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter element layer is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. In the process of filtration, the filter element filters ...
